Can we skip some pre-defined Frames while rendering, to prevent blender from re-rednering the same scene?
If your output is set to be .png images (which is recommended) you can change the duration of any frame of your choice in the video editor. If you want your output to be video you can set the Frame Start and End in the Scene Tab, render the first sequence, then the frame where you want to stop, and for last render the rest of the animation. after that, you would put everything together in the video editor.
